I I 1 Claim. This invention relates to new and useful improvements in mailing devices and more particularly-tit pertains to a new and improved combination mailing and return envelope. 5 -It is an object of the invention to provide a combined mailing and return envelope which may be constructed from a single blank of material, whereby a minimum amount of material is required.

It is a further object of the invention to provide a device of the above mentioned character in which the two envelopes are secured to each other untilsuchtilneasit is desiredtouse the returnenvelope for mailingpurposes.

It is a still further object of the invention so to construct the envelopes, that one of them is adapted to be folded into the other in the manufacture of the device, which position it occupies until such time as it is ready for use when it may 20 be from the outer envelope and detached Other objects will appear as the nature of the invention is better understood and reference will 'Flgurelisaplanviewofablankfromwhich a mailing'dsvice constructed in accordance with blankisperforated. scored,creasedorotherwise when the blank is folded along the line I5. Projecting from another marginal edge there is an extension I which folds inwardly ofthe section II on the line I1, and which; together with the extension ll, which folds inwardly of. the section 5 I I4 upon the line i9, forms the back of the mailing envelope. These extensions I6 and I8 are shown in their infolded positions in Figure 2, and it will be noted that in these positions, the extension l8- overlies the extension It. A suitable adhesive 20 is employed to secure the flaps l6 and I8 in overlapped relation. The sealing flap it bears adhe-- sive 21 by which it may be sealed closed.

Projecting from one of the marginal edges of the section ii there is an extension 30 which, when folded upon the line 3|, forms a sealing flap for the return envelope. Projecting from the opposite marginal edge of the blank I! there is an extension 32 which, when folded upon the line 33,.forms the hacker rear wall of the return envelope. Opposite edges of the extension 32 may be provided with adhesive as designated at 34 and 35. The adhesive 34 and the adhesive 35 form the means-by which the extension 32 may be secured to the section I! toform the return envelope. The sealing flap is provided with adhesive 36 by which it may be sealed closed.

In forming the mailing device from the blank shownin Figure 1, the two extensions l6 and I8 of the section ii, are folded inwardly and secured 30 together as heretofore described and the extension 32 is folded inwardly of the section l2 and secured thereto. The device will then appear as it is shown in Figure 2. It will be noted by examination of the drawing that the section I! is slightly 5 "narrower than the section II, theline of fold 32 being slightly-out of line with its respective lineof fold Ii, as indicated at 4| in Figure 2. I

' By this construction, the return envelope which is formed from the section l2, will be slightly 40 smaller than the mailing envelope in order that it may be received therein, audit is this position which the return envelope occupies in the finished form of the device. To position the "return envelope within the mailing envelope, the blank'is folded upon the line I I, and the device appears as illustrated in Figure 3. I

Figure 3 illustrates the complete device ready for use and in use, a letter, circular or the like is inserted into the mailing envelope along with the return envelope and the sealing flap M of the mailing envelope is sealed closed for mailing. The recipient removes both the enclosure and the return envelope upon opening of the mailing envelope and if he desires to use the return enwhereupon it is free for use.

By examination of Figure 4 of the drawing, it will be apparent that a portion 45 of the return envelope is visible at the rear of the mailing envelope and that in reality, the return envelope forms the back of the mailing envelope when it is in position within the mailing envelope.

It will also be noted that the front face of the return envelope is presented to the under side of the sealing flap ll of the mailing envelope when the return envelope is in position within the mailing envelope. 'This is important, since it protects the sealing flap of the return envelope against damage by an instrument inserted beneath 'the sealing flap oi the mailing envelope toopen the mailing envelope.

While the invention has been herein illustrated in its preferred form, it is to be understood that the invention is not to be limited to the specific form in which it is shown and that it may be practiced in other forms without departing from the spirit thereof.

Having thus described the invention, what is claimed as new; is:

A combined mailing and return envelope comprising two individual envelopes formed oi a single blank, each 01' said envelopes including a body and flap portions, said mailing envelope being larger for receiving the return envelope, the body portions .of said envelopes being connected along one edge and provided with a row of periorations forming both the line of severance and line of fold of said envelopes for folding the return envelope in the mailing envelope, one of the flaps of said return envelope being sealed adjacent the line of perforations, the flaps oi the mailing envelope cooperating when folded upon.

its body to cover the major portion of the return envelope and to seal the same in the mailing envelope, the uncovered portion 01' the return envelope providing a finger gripping area to facilitate its removal in unsevered condition upon'the opening of either the top or bottom flaps of the mailing envelope.
